Wedge wire engineering guides
Our engineering guides explain how wedge wire screens work and how to specify one: slot size and open area, profile wire and support rods, flow direction, materials, and the design calculations behind each screen. Each guide gives the formula, a worked example and the data to send with your enquiry.
What is a wedge wire screen? An engineering guide
A wedge wire screen is a screening surface made of V-shaped profile wire welded to support rods at every intersection.

Centrifuge basket design for sugar, coal and minerals
Centrifuge basket design starts with the machine type, whether batch, continuous or vibrating basket.
Read the guide Choosing a wedge wire screen material, from SS 304 to Hastelloy
Wedge wire screen material is selected from the chloride level, temperature, pH and crevice conditions of the process.
Read the guide Header lateral underdrain design for ion exchange and filter vessels
Header lateral underdrain design addresses three functions, which are to retain the media, collect treated water evenly and distribute backwash evenly across the vessel floor.
Read the guide How to choose wedge wire slot size and open area
Wedge wire slot size is the clear gap between adjacent profile wires at the screen face.
Read the guide How to clean wedge wire screens and maintain the slot
Wedge wire screens are cleaned from the outlet side first, by backwash, air scour or a low-angle water jet, so that particles lift off the slot face, and the face is then brushed along the wires, never across them.
Read the guide How to write a wedge wire screen specification
A complete wedge wire screen specification states the process conditions first: fluid, flow, temperature, pressure and the solids to be retained.
Read the guide How wedge wire screens are made, from wire to inspection
How wedge wire screens are made determines how accurately they hold their slot in service.
Read the guide Intake screen design and sizing for through-slot velocity
Intake screen design starts from the design flow and the allowed through-slot velocity.
Read the guide Lauter tun false bottom design with wedge wire and milled plate
Lauter tun false bottom design starts from the grain bed the floor supports and the wort it drains evenly to the run-off pipes.
Read the guide Mesh to micron conversion chart and how mesh relates to slot size
A mesh to micron conversion chart turns a sieve number into its opening.
Read the guide Rooftop rainwater harvesting filter design, from roof area to filter
Rainwater harvesting filter design starts from the peak flow off the roof, which is roof area multiplied by design rainfall intensity and runoff coefficient.
Read the guide Sieve bends (DSM screens): how they work and how they are sized
A DSM screen, or sieve bend, is a static curved wedge wire screen with its slots set across the flow.
Read the guide The EN 10204 3.1 mill test certificate and other screen quality documents
An EN 10204 3.1 mill test certificate is the inspection document in which the material manufacturer reports chemical and mechanical test results for the actual heat supplied, validated by an inspector independent of production.
Read the guide Water well screen design by slot, length and entrance velocity
Water well screen design follows four steps.
Read the guide Wedge wire flow direction and the four flow configurations
Wedge wire flow direction defines how a screen performs.
Read the guide Wedge wire screen design calculations: the engineering behind a screen
A wedge wire screen design calculation covers hydraulics first, through open area, through-slot velocity, screen area and pressure drop, and structure second, through collapse resistance, panel deflection and tensile load.
Read the guide Wedge wire screen sizes and how to choose profile wire and rods
Wedge wire screen sizes are defined by four numbers: profile wire, support rod, slot and diameter.
Read the guide Wedge wire terms, from abrasion to wrap wire
Wedge wire terms are defined here from A to Z for engineers who specify, buy or maintain screens.
Read the guide Wedge wire vs perforated plate vs wire mesh, compared for engineers
Wedge wire vs perforated plate is decided mainly by clogging and load.
Read the guide What is a resin trap? Selection for ion exchange and DM plants
A resin trap is an inline wedge wire strainer on the outlet of an ion exchange vessel that catches whole resin beads if a lateral or nozzle fails.
